TBU™ P500-G and P850-G Protectors
Transient Blocking Units - TBU™ Devices
Bourns® Model P500-G and P850-G
TBU™ products are high speed, surge
protection components designed to
protect Subscriber Line Interface Circuits
(SLICs) against transients caused by
AC power cross, induction and lightning
surges.
Agency Approval
UL recognized component File # E315805.
The TBU™ device blocks surges and
provides an effective barrier behind
which sensitive electronics are not
exposed to large voltages or currents
during surge events.

NC = Solder to PCB; do not make electrical

TBU™ devices have matte-tin termination finish. Suggested layout should use non-solder mask
define (NSMD). Recommended stencil thickness is 0.10-0.12 mm (.004-.005 in.) with stencil
opening size 0.025 mm (.0010 in.) less than the device pad size. As when heat sinking any power
device, it is recommended that, wherever possible, extra PCB copper area is allowed. For minimum parasitic capacitance, do not allow any signal, ground or power signals beneath any of the
pads of the device.
